 ACE model

The ACE model decomposes trait variation into additive genetic effects $A$, common environmental effects $C$, and unique environmental effects $E$.

The ACE model typically refers to the "ACE" (Adverse Childhood Experiences) framework, which is used to understand the impact of childhood trauma on long-term health and well-being. This model emphasizes the correlation between adverse experiences in childhood—such as abuse, neglect, and household dysfunction—and various negative outcomes later in life, including physical and mental health problems. However, "ACE" can also refer to other contexts depending on the specific field.
